The SV roadster weighs 110 pounds less than the LP 700-4. Using the same 6.5-liter V12 as the hardtop, the SV roadster comes in with a power-to-weight ratio of 4.6 pounds per horse. Output stays at 740 hp at a stratospheric 8,400 rpm. Torque is rated at 509 lb-ft. A hard-shifting, if it’s anything like the hardtop, seven-speed ISR transmission sends power to all four wheels.

As with the coupe, the SV roadster comes with a magneto-rheological suspension, which can be firmed up or softened on demand, a pushrod damping system and Lamborghini’s adjustable steering.

The SV roadster gets a two-piece hardtop made from carbon fiber, both weighing less than 13 pounds. They stow in the luggage compartment, handy for when you’re out on the road and the rains start falling.
